Abstract
An insulation system of a current-carrying conductor of an electric machine. The insulation system comprises a thermally curable resin including a polymer resin matrix and a nanoparticulate filler. A mica paper or mica tape is impregnated with the thermally curable resin. The thermally curable resin comprises nanoparticulate filler, the total quantity of nanoparticulate filler being at least 0.1 wt % and not more than 0.5 wt %.
Claims11
An insulation system of a current-carrying conductor of an electric machine, the insulation system comprising:
- a thermally curable resin including a polymer resin matrix and a nanoparticulate filler;
- and
- a mica paper or mica tape impregnated with the thermally curable resin,
- wherein the thermally curable resin comprises nanoparticulate filler, the total quantity of nanoparticulate filler being at least 0.1 wt % and not more than 0.5 wt %.
A method for producing an insulation system on a current-carrying conductor within an electric machine, the method comprising:
- providing a mica paper or mica tape;
- wrapping the current-carrying conductor with the mica paper or mica tape;
- providing a polymer resin comprising nanoparticulate filler thoroughly mixed therein, the total quantity of nanoparticulate filler being at least 0.1 wt % and not more than 0.5 wt %;
- fully impregnating the mica paper or mica tape with the polymer resin;
- and
- thermally curing the polymer resin that impregnates the mica paper or mica tape.
